Refill
The refill process is automatically controlled by the
pressure limits as defined under settings. Available in the
direct refill version (-R) or the break tank refill version (-B).
The net refill flow depends on water supply pressure (-R
versions) and system pressure.
6.7
Low pressure refill
When the system pressure has dropped to a value below
the minimum operating pressure (1 bar), a low pressure
warning will occur and the unit will ask whether a special
refill procedure will be started to bring the system to the
refill pressure again. In this manual refill cycle, the pump
will be switched on and off and the refill valve will stay
open.
6.8
Various remarks
When the unit is connected to mains power, the
display is shown automatically after touching the
screen.
The display switches off automatically after not
being touched for 5 minutes.
The degassing or refilling process is stopped by a
stop procedure, making sure that the unit stops in a
safe situation (overpressure). This stopping
procedure may take some time (max. 20 seconds).
When a pump has not run for 96 hours, an
automatic pump test (15 seconds) will run at the
next Auto degass time.
NOTE
The start page shows on the display.
NOTE
The unit is standby.
NOTE
The new setting parameter shows on the
display.
NOTE
The unit stops.
NOTE
Every degassing cycle will start in the pump
test mode, which is the rinsing phase. After
15 seconds, the degassing mode will appear
and the degassing cycle will start (vacuum
phase).
CAUTION
Manually started degassing will not be
controlled by the Smart switch nor by
blocking times and will run continuously.
NOTE
Now the degassing process is controlled by
the Smart switch and will start again at the
next Auto degass time. A new degassing
action always starts with a pump test as a
part of the degassing cycle.
The refill process always has priority over the
degassing process. As soon as system
pressure drops below the “refill pressure”,
the refill process will start.
